that doesn't have a very long history. i like the history of gold of course because it's a little bit longer. >> right. >> but if the bitcoin fits the bill, and there is no fraud involved, i think, yes, it can be a participant and there will be other currencies similar to this, i think, as time goes on. the thing that surprised me the most was the, sort of the acceptance by bernanke, not saying, yyu know, that this was a terrible thing. he said, ttis sounds pretty good. we have to consider this as a possibility. he was much more adamant when i asked him about gold. he said absolutely not. gold is not money. maybe bitcoin is. and i just wonder whether it is less threatening to the central bank. that makes me think about what is going on at this point. melissa: do you think it is really less threatening, bitcoin? what is interesting about it, the government has control more or less over the dollar. like you're saying they could lose control through their own actions but for now, they're trying to manage the value.
